Design for Testability
نویسنده
چکیده
Testability is a software quality characteristic that is of major relevance for test costs and software dependability. Still, testability is not an explicit focus in today’s industrial software development projects. Related processes, guidelines, and tools are missing. This paper is about design for testability, the main intersection of software design and testing. We describe 1) elements of object-oriented software design that may cause testing problems and 2) guidelines on how to improve testability including the use of design patterns. The special focus is on system dependencies and observability.

Measuring testability early in the development life cycle especially at design phase is a criterion of crucial importance to software designers, developers, quality controllers and practitioners. However, most of the mechanism available for testability measurement may be used in the later phases of development life cycle. Early estimation of testability, absolutely at design phase helps designe...

متن کاملAn Empirical Study on Testability Measurement of Object Oriented Software
Testability has always been a difficult exercise and its accurate estimation or assessment a complex exercise. Most of the studies quantify testability or more specifically the attributes that have influence on software testability but at the implementation level. A decision to transform the design in order to improve software testability after implementation has started may be very error prone...
